2. Antimicrobial effect: Ginger extract has obvious inhibitory effect on Staphylococcus aureus, Staphylococcus albus, Salmonella typhi, Shigella sonnei and Pseudomonas aeruginosa in a concentration-dependent manner. Staphylococcus aureus and Staphylococcus albus have the strongest inhibitory effect. After the interaction between ginger root extract and HBsAg1~ 3 hours, the P/N value of HBsAg can be significantly reduced. But after more than 3 hours, the descending speed will not increase. The water extract of ginger has strong bactericidal effect on typhoid Bacillus and Vibrio cholerae in vitro, and has inhibitory effect on Trichophyton in vitro. Gingerol and gingerol in ginger rhizome can kill mollusks and schistosomiasis, and can be used to treat schistosomiasis.
3. Antioxidant effect: Studies show that ginger has antioxidant effect. Adding 5% ~ 10% ginger slices to fat pork and boiling for 1 ~ 4 hours can prevent pork from spoilage. The peroxide value (POV) and thiobarbituric acid value (TBA) of fat meat cooked by this method for 4 hours are similar to those of fresh fat pork. Pork cooked with 20% or 50% ginger for 4 hours and cooked at 30℃ for 90 days has almost no change in POV and TBA. The water, ethanol and ether extracts of ginger also significantly inhibited the oxidation of potassium linoleate. It has also been reported that adding active oxygen scavenger or ginger extract can inhibit DNA damage caused by lipid peroxidation. Ginger extract can also inhibit the production of reactive oxygen species and the oxidation of linoleic acid.
4. Other effects: Ginger paste and ginger extract can obviously promote wound healing. Ginger juice can inhibit the growth of cancer cells to some extent. Adding ginger extract to some antitumor drugs can reduce the side effects of antitumor drugs. Ginger has obvious blocking effect on nitrosation reaction under simulated gastric juice conditions, and its effective component for inhibiting nitrite synthesis is stable to heat, and it still maintains quite strong activity after long-term heating in boiling water. Ginger extract has antiallergic effect and can prevent anaphylactic shock and urticaria caused by protein in some fish.
Second, the medicinal value of ginger
1, refreshing: Ginger has a refreshing effect. When suffering from heatstroke in summer, giving patients a cup of ginger juice can make them wake up quickly and have a good effect of relieving summer heat.
